Biology
(
englanti
)
tarjonnut Fishbase
Most abundant on silty-sand or muddy substrates. Large adults feed near gutters and sandbars inside Shark Bay and move into deeper waters of marine embayments. Juveniles frequent seaweed banks and broken bottom and occur in large numbers near mangrove creeks. They enter coastal rivers in the Swan and Mandurah estuaries in western Australia. Oviparous (Ref. 205), and are multiple spawners with synchronous development (Ref. 36823). Juveniles and adults are commonly trawled with S. robusta and S. lutea (Ref. 6205). Marketed fresh (Ref. 9679).
